Question from Jennifer

Hi Debra,

Does anyone know if silicone touted as antibacterial and antimicrobial is that way because it is naturally a deterrent or if it is treated with a chemical? And if treated with a chemical to be antibacterial, is it inert in silicone in the final product?

I can’t find any information online about it at all for non medical products. For example I’m looking at buying a silicone dish drying mat because the cloth ones just get moldy fast and they all seem to say they are antimicrobial, but I can’t determine why, if it is a natural byproduct of being silicone or if treated like so many things are now.

If my dishes that eat off of will be touching I was wondering if I should be concerned. Thanks!

Antibacterials is a big subject and antibacterials can range in toxic effect from silver having virtually no health effects to triclosan, which is known to be an endocrine disruptor and cause skin and breast cancer, among other health effects. There is even now an antimicrobial made from peppermint oil, so whenever you see the word “antimicrobial,” you need to find out the specific antimicrobial that has been used.

Antibacterials may be widely used and not on the label, for they can be used to prevent the deterioration of plastics, for example, which would not be on the label because it’s not a selling point for consumers. Again, the antimicrobial may be perfectly harmless or have health effects.

With regards to your question as to whether silicone is inherently antibacterial or whether a chemical is added, I would say from looking at online search results that silicone is NOT inherently antibacterial because additives exist to make silicone antibacterial for specific uses.

Would the antibacterial leach from the silicone? Well, depending on what form the antibacterial comes in, it would likely bind to the silicone and not be released. But again, we don’t know the antibacterial or the form it is in, or its toxicity.

I’m using my best logic here, based on my understanding, not on tests.

I always apply the Precautionary Principle, which is, when in doubt, don’t use it.

This is another example of why there needs to be improved labeling that reveals what all the materials are.

Question from Caroline

Hi Debra,

My home is prone to ants; and this time , as well as regular foundation spraying with Termidor, and placing advion ant bait in heavily infested areas within the home 3 x over the past month, it has been over a month that the ants invade the master bath daily to the point of being unusable. Usual spraying of vinegar and water, sprinkling black pepper or cinnamon was to no avail. I had to call in a professional exterminator who is trying to work with me because of MCS.

I’m going to say something that may sound obvious, but have you tried filling the holes where they come into the house?

This has been my tried-and-true method for controlling ants for almost 40 years and it always works. I even did it when I lived in an apartment building in San Francisco. All the other units were sprayed for ants, but I wouldn’t let them in my unit and did this instead. Even with the spraying the other units had ants. Mine was the only one that did not.

All you need is a bottle of Elmer’s White Glue and a damp sponge.

Trace the line of incoming ants back to where they are coming into your house and make note of the spot. Then wipe up the ants with the sponge. Fill in the hole with Elmer’s Glue. Then go to the next entrance and do the same.

The ants will continue to find new ways to get in until you’ve sealed all the holes. Then you will never have an ant problem again.
